Application of Electrical Stimulation in BCI in Patients with Alzheimer’s Disease

This paper systematically discusses the application prospect of neuromodulation technology in the treatment of Alzheimer’s disease (AD). It focuses on the potential role of various techniques, including transcutaneous electrical nerve stimulation (TENS), deep brain stimulation (DBS), repeated transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS), in improving the cognitive function of AD patients. With the aggravation of the global aging problem, the incidence of AD is increasing year by year, and the existing treatment methods are difficult to effectively prevent the progress of the disease. Studies have shown that technologies such as TENS and DBS can improve patients’ memory and cognitive function to some extent. For example, a study by Smith et al. (2020) found that DBS applied to the fornix resulted in a 20% improvement in memory scores over a 6-month period. However, due to the small sample size and inconsistent experimental design, the universality and reliability of the existing research results are still limited. Future studies should aim for larger, more diverse sample sizes and standardized experimental protocols to enhance the robustness of findings. This article reviews the latest research results of these neuromodulation techniques, emphasizing the importance of optimizing treatment parameters and expanding the scale of clinical trials. The paper is structured as follows: first, this paper discusses each neuromodulation technique in detail; then, this paper analyzes their potential benefits and limitations; finally, this paper provides recommendations for future research directions.

Reduced Graphene Oxide-Substituted Nanohydroxyapatite: Rejuvenating Bone-Nerve Crosstalk with Electrical Cues in a Fragility Fracture Rat Model under Hyperglycemia.

Diabetes has currently acquired the status of epidemic worldwide, and among its various pathological consequences like retinopathy and nephropathy, bone fragility fractures from diabetic osteopathy occurs in later stages and is equally destructive. Chronic hyperglycemia culminates into deteriorating microvasculature and quality of bone, making it prone to fractures. Among these, hip fractures are most common, especially in older diabetic patients apart from underlying neuropathy. Our study is an attempt to ameliorate hip fragility fracture and nerve trauma with electrical stimulation as an interface in a chronic diabetic rat model. We have fabricated reduced graphene oxide-substituted hydroxyapatite as an electroactive bone substitute and incorporated it into chitosan gelatin cryogels. The in situ reduction of graphene oxide during sintering of hydroxyapatite imparts higher potential to the fabricated composite in dealing with problem at question. The cryogels depicted optimum in vitro biocompatibility and enhanced mineralization after ectopic subcutaneous implantation in rats. The therapeutic potency of composite cryogels was evaluated in a hip fracture model with compression to the sciatic nerve in diabetic rats, mimicking the severe clinical trauma. The presence of cryogels in the femoral neck canal coupled with electrical stimulation and biochemical factors significantly improved bone regeneration in diabetic rats as depicted with microcomputed tomography analysis and histology images. The application of electrical stimulation also ameliorated the nerve trauma observed with 70% improvement in electrophysiological parameters such as the compound muscle action potential with combinatorial therapy. We therefore report the successful implication of a multitarget therapy in a chronic diabetic rat model unraveling the bone-nerve crosstalk with electroactive smart cryogels.

Anticancer potentiality of Hottentotta saulcyi scorpion curd venom against breast cancer: an in vitro and in vivo study.

Scorpion venom may include pharmacological substances that have the potential to provide benefits. Multiple scientific investigations have shown that particular scorpion venoms induce apoptosis and inhibit the development of cancerous cells. The present study investigated the potential anticancer properties of the crude venom derived from Hottentotta saulcyi (H. saulcyi) on both in vivo mice models and in vitro breast carcinoma cells. The venom of scorpions belonging to the species H. saulcyi was obtained with the application of electrical stimulation at voltages of 8 and 10V. The determination of the Average Lethal Dose 50 (LD50) was conducted. The present work assessed the in vitro cytotoxicity and morphological characteristics of H. saulcyi venom using fluorescence microscopy, MTT assay, and flow cytometry assessment. Additionally, research was performed to assess the cytotoxic effects in vivo on a mouse model with breast cancer. The examination of MCF-7 cells treated with scorpion venom at a microscopic level revealed the existence of cells undergoing apoptosis. The venom of H. saulcyi has anticancer properties, as shown by the observation that MCF-7 cells had a 62.12% apoptotic rate when exposed to a dose of 1.47mg/L. Based on the results obtained, it can be shown that the viability of MCF-7 cells has exhibited a substantial reduction (P < 0.01). Furthermore, the findings indicated that the venom of H. saulcyi resulted in a significant increase in the synthesis of TNF-α, IL-6, IL-10, TGF-β, and caspase (P < 0.05). The treatment groups administered with H. saulcyi venom exhibited a significant augmentation in the expression of proapoptotic genes compared to the control group of healthy individuals. The transcription of the BCL2 gene exhibited a statistically significant increase in the healthy control group compared to both the healthy venom-treated group (P < 0.05) and the malignant venom-treated group (P < 0.01). The crude venom of H. saulcyi has considerable promise in demonstrating anticancer properties. Further investigation may be warranted to explore the potential of using H. saulcyi crude venom as a medicinal platform for the prevention of breast cancer.

Investigating the Effect of Polypyrrole-Gelatin/Silk Fibroin Hydrogel Mediated Pulsed Electrical Stimulation for Skin Regeneration.

In clinical practice to treat complex injuries, the application of electrical stimulation (ES) directly to the skin complicates the wound. In this work, the effect of a conductive hydrogel mediated electric field on skin regeneration is investigated. Polypyrrole incorporated matrices of gelatin and silk fibroin were prepared by two-step interfacial polymerization. The maximum electrical conductivity of 10-4 S cm-1 was achieved when 200 mM polypyrrole was loaded. Mechanically stable and cytocompatible hydrogels were evidenced to have antioxidant and blood compatible characteristics. Human dermal fibroblast cells responded to pulsed stimulation of 100 or 300 mV mm-1 as observed from the increased expressions of TGFβ1, αSMA, and COLIAI genes. Further, the increase in the αSMA protein expression with the magnitude of electrical stimulation also suggested transdifferentiation of the fibroblast to myofibroblast. Moreover, Raman spectroscopy identified two fingerprint regions (collagen and lipid) to differentiate ES treated and nontreated samples. Therefore, the combination of hydrogels and electrical stimulation has potential therapeutic effects for accelerating the rate of skin regeneration.

Clinical Efficacy of Auricular Vagus Nerve Stimulation in the Treatment of Chronic and Acute Pain: A Systematic Review and Meta-analysis.

Current guidelines for pain treatment recommend a personalized, multimodal and interdisciplinary approach as well as the use of a combination of drug and non-drug therapies. Risk factors for chronification should already be reduced in patients with acute pain, e.g., after surgery or trauma. Auricular vagus nerve stimulation (aVNS) could be an effective non-drug therapy in the multimodal treatment of chronic and acute pain. The aim of this systematic review and meta-analysis is to evaluate the clinical efficacy and safety of aVNS in treating chronic and acute pain conditions. A systematic literature search was performed regarding the application of auricular electrical stimulation in chronic and acute pain. Studies were classified according to their level of evidence (Jadad scale), scientific validity and risk of bias (RoB 2 tool) and analyzed regarding indication, method, stimulation parameters, duration of treatment and efficacy and safety. A meta-analysis on (randomized) controlled trials (using different comparators) was performed for chronic and acute pain conditions, respectively, including subgroup analysis for percutaneous (pVNS-needle electrodes) and transcutaneous (tVNS-surface electrodes) aVNS. The visual analog pain scale (VAS) was defined as primary efficacy endpoint. A total of n = 1496 patients were treated with aVNS in 23 identified and analyzed studies in chronic pain, 12 studies in acute postoperative pain and 7 studies in experimental acute pain. Of these, seven studies for chronic pain and six studies for acute postoperative pain were included in the meta-analysis. In chronic pain conditions, including back pain, migraine and abdominal pain, a statistically significant reduction in VAS pain intensity for active compared to sham aVNS or control treatment with an effect size Hedges' g/mean difference of - 1.95 (95% confidence interval [CI]: - 3.94 to 0.04, p = 0.008) could be shown and a more favorable effect in pVNS compared to tVNS (- 5.40 [- 8.94; - 1.85] vs. - 1.00 [- 1.55; - 0.44]; p = 0.015). In acute pain conditions, single studies showed significant improvements with aVNS, e.g., in kidney donor surgery or tonsillectomy but, overall, a non-statistically significant reduction in VAS pain intensity for active compared to sham aVNS or control with - 0.70 [- 2.34; 0.93] (p = 0.15) could be observed in the meta-analysis. In acute pain results vary greatly between studies depending especially on co-medication and timepoints of assessment after surgery. A significant reduction in analgesics or opiate intake was documented in most studies evaluating this effect in chronic and acute pain. In 3 of the 12 randomized controlled trials in patients with chronic pain, a sustainable pain reduction over a period of up to 12months was shown. Overall, aVNS was very well tolerated. This systematic review and meta-analysis indicate that aVNS can be an effective and safe non-drug treatment in patients with specific chronic and acute postoperative pain conditions. Further research is needed to identify the influence of simulation parameters and find optimal and standardized treatment protocols while considering quality-of-life outcome parameters and prolonged follow-up periods. A more standardized approach and harmonization in study designs would improve comparability and robustness of outcomes.

Application of Transcutaneous Electrical Nerve Stimulation (TENS) in Stroke Rehabilitation: An Umbrella Review

Application of Transcutaneous Electrical Nerve Stimulation (TENS) in Stroke Rehabilitation: An Umbrella Review

Influence of stimulation parameters on torque development during the combined application of electrical nerve stimulation and muscle lengthening.

This study investigated the influence of stimulation parameters on torque production when combining a brief muscle lengthening with electrical stimulation. Fifteen volunteers participated in one experimental session where two distinct stimulation modalities were compared: wide-pulse high-frequency (WPHF, pulse duration: 1ms, frequency: 100Hz), favouring afferent pathways activation, and narrow-pulse low-frequency (NPLF, pulse duration: 0.05ms, frequency: 20Hz), favouring activation of the efferent pathway. Both stimulation modalities, were applied to evoke 5-10% of maximal voluntary contraction either in isometric conditions (WPHF and NPLF) or in combination with a muscle lengthening (lengthening condition: WPHF+LEN and NPLF+LEN). The torque-time integral (TTI) during the stimulation trains and the muscle activity after the cessation of the stimulation trains (sustained EMG activity, normalized to the maximal EMG activity) were assessed and compared between the stimulation modalities and the conditions (two-way ANOVA). An interaction effect was obtained, revealing significant differences in TTI and sustained EMG activity between the WPHF+LEN and the other tested conditions (P=0.048 and P=0.044, respectively). TTI and sustained EMG activity were higher for WPHF+LEN (228.4±105.3 Nm.s and 0.085±0.070, respectively) compared to WPHF (168.4±72.9 Nm.s; 0.052±0.026), NPLF+LEN (136.4±38.9 Nm.s; 0.031±0.016) and NPLF (125.2±36.1 Nm.s; 0.028±0.015). The increased TTI during the WPHF+LEN condition suggests that the contribution of afferent pathways to the evoked torque can be enhanced with the muscle lengthening superimposition. They highlight the importance of using WPHF stimulation that already solicits Ia afferents to benefit from the cumulative afferent activation induced by the muscle lengthening to further increase torque production.

Amelioration of Focal Hand Dystonia via Low-Frequency Repetitive Somatosensory Stimulation.

Dystonia presents a growing concern based on evolving prevalence insights. Previous research found that, in cervical dystonia, high-frequency repetitive somatosensory stimulation (RSS; HF-RSS) applied on digital nerves paradoxically diminishes sensorimotor inhibitory mechanisms, whereas low-frequency RSS (LF-RSS) increases them. However, direct testing on affected body parts was not conducted. This study aims to investigate whether RSS applied directly to forearm muscles involved in focal hand dystonia can modulate cortical inhibitory mechanisms and clinical symptoms. We applied HF-RSS and LF-RSS, the latter either synchronously or asynchronously, on forearm muscles involved in dystonia. Outcome measures included paired-pulse somatosensory evoked potentials, spatial lateral inhibition measured by double-pulse somatosensory evoked potentials, short intracortical inhibition tested with transcranial magnetic stimulation, electromyographic activity from dystonic muscles, and behavioral measures of hand function. Both synchronous and asynchronous low-frequency somatosensory stimulation improved cortical inhibitory interactions, indicated by increased short intracortical inhibition and lateral spatial inhibition, as well as decreased amplitude of paired-pulse somatosensory evoked potentials. Opposite effects were observed with high-frequency stimulation. Changes in electrophysiological markers were paralleled by behavioral outcomes: although low-frequency stimulations improved hand function tests and reduced activation of dystonic muscles, high-frequency stimulation operated in an opposite direction. Our findings confirm the presence of abnormal homeostatic plasticity in response to RSS in the sensorimotor system of patients with dystonia, specifically in inhibitory circuits. Importantly, this aberrant response can be harnessed for therapeutic purposes through the application of low-frequency electrical stimulation directly over dystonic muscles. © 2024 The Author(s).

Analyzing the Role of Transcutaneous Electrical Nerve Stimulation in Sports: A Literature Perspective on Its Application and Benefits in Physiotherapy

This study evaluates the application of Transcutaneous Electrical Nerve Stimulation (TENS) in sports physiotherapy, focusing on pain management, muscle recovery, and injury rehabilitation. Utilizing qualitative descriptive research based on a literature review, data were sourced from reputable scientific databases such as Scopus, ScienceDirect, and Google Scholar. The analysis revealed that TENS effectively manages pain by altering pain signals before they reach the brain, enhances muscle recovery by improving blood circulation, reducing inflammation, and accelerating healing. Additionally, TENS supports injury rehabilitation by preserving strength and muscle mass during immobilization and contributes positively to athletes' mental well-being by maintaining motivation. While TENS demonstrates various benefits, its effectiveness can vary among individuals, indicating a need for further research to optimize usage protocols and assess its impact on specific conditions in sports. In conclusion, TENS is a valuable tool in sports physiotherapy, offering significant advantages in pain relief, muscle recovery, and rehabilitation

Decreases in mucosally-evoked tachykinin signaling pathways can explain age-related reductions in murine colonic motility patterns.

Increasing age increases the incidence of chronic constipation and fecal impaction. The contribution of the natural aging process to this phenotype is unclear. This study explored the effects of age on key motility patterns in the murine colon and determined the contribution that altered neurokinin 2 (NK2) -mediated signaling made to the aging phenotype. Mucosal reflexes, colonic migrating motor complexes (CMMCs) and colonic motility assays were explored in isolated exvivo colons from 3, 12-14, 18- and 24-months old mice and the NK2-mediated response determined. Electrical field stimulation (EFS) or exogenous drug application were used to explore the role of the mucosa in colonic segments. Aging reduced the force of contraction of the distal colon mucosal reflex, the frequency and force of contraction of CMMCs and the NK2-mediated component of both motility patterns. Ondansetron, a 5-HT3 receptor antagonist, blocked a component of both motility patterns in full thickness but not in mucosa-free segments of the distal colon. 5, hydroxytryptamine (5-HT) and EFS-evoked NK2-dependent contractions were reduced with increasing age. Smooth muscle sensitivity to 5-HT or neurokinin A (NKA) was not altered with age. In isolated colon motility assays application of NKA decreased transit time in 24-months colon and the NK2 antagonist GR159897 increased transit times in both 3- and 24-months old colons. Aging impairs key motility patterns in the murine colon. These changes involve a decrease in mucosally-evoked NK2-mediated signaling. Targeting NK2-mediated signaling may provide a novel approach to treating age-related motility disorders in the lower bowel.

Preservation of vision by transpalpebral electrical stimulation in mice with inherited retinal degeneration.

The potential neuroprotective and regenerative properties of electrical stimulation (ES) were studied in rhodopsin knockout mice (Rho -/- ), a murine model of inherited retinal degeneration. The study focused on assessing the impact of varying ES frequencies on visual functions and photoreceptor cell survival in Rho -/- mice. To elucidate the impact of electrical stimulation on cone survival, Rho -/- mice received either sham or transpalpebral ES using biphasic ramp or rectangular waveforms at 100µA amplitude, starting at sixweeks of age. The treatment duration spanned from one to three weeks. The optimal treatment frequency of ES sessions was determined by applying ES every one, two, or three days in three separate groups of Rho -/- mice. The sham group received daily treatments without the application of ES. Our study revealed significant improvement of visual function in Rho -/- mice following daily or every-other-day noninvasive transpalpebral ES, as evidenced by electroretinogram and optomotor response-based visual behavior assays. Concurrently, assessment of outer nuclear thickness and immunohistochemistry for the cone photoreceptor cell marker PNA demonstrated pronounced increases in the survival of rods and cones and improvement in the morphology of the inner and outer segments. This study underscores the protective effect of non-invasive ES in rhodopsin knockout-induced retinal degenerative disorders, providing a foundation for developing targeted therapeutic interventions for retinitis pigmentosa.

Electrical Stimulation Promotes Endocytosis of Magnetic Nanoparticles by Cancer Cells.

Nanomaterials are increasingly used in biomedical imaging and cancer therapy, and how to improve the endocytosis of nanomaterials by cells is a key issue. The application of alternating current (AC) electrical stimulation to osteosarcoma cells (MG-63) here can increase the cellular endocytosis of Fe3O4 nanoparticles (diameter: 50nm) by 52.46% via macropinocytosis. This can be ascribed to the decrease in F-actin content and the increase in intracellular Ca2+ concentration. Transmission electron microscope, immunofluorescence staining, western blot, flow cytometry, and inductively coupled plasma emission spectrometer analyses support this interpretation. The application of electrical stimulation decreases the cell viability in magnetic hyperthermia by 47.6% and increases the signal intensity of magnetic resonance imaging by 29%. Similar enhanced endocytosis is observed for breast cancer cells (MCF-7), glioblastoma cells (U-87 MG), melanoma cells (A-375), and bladder cancer cells (TCCSUP), and also for Fe3O4 nanoparticles with the diameters of 20 and 100nm, and Zn0.54Co0.46Cr0.65Fe1.35O4 nanoparticles with the diameter of 70nm. It seems the electrical stimulation has the potential to improve the diagnostic and therapeutic effects of magnetic nanoparticles by promoting endocytosis.

Engineering 3D Scaffold-Free Nanoparticle-Laden Stem Cell Constructs for Piezoelectric Enhancement of Human Neural Tissue Formation and Function.

Electrical stimulation (ES) of cellular systems can be utilized for biotechnological applications and electroceuticals (bioelectric medicine). Neural cell stimulation especially has a long history in neuroscience research and is increasingly applied for clinical therapies. Application of ES via conventional electrodes requires external connectors and power sources, hindering scientific and therapeutic applications. Here engineering novel 3D scaffold-free human neural stem cell constructs with integrated piezoelectric nanoparticles for enhanced neural tissue induction and function is described. Tetragonal barium titanate (BaTi03) nanoparticles are employed as piezoelectric stimulators prepared as cytocompatible dispersions, incorporated into 3D self-organizing neural spheroids, and activated wirelessly by ultrasound. Ultrasound delivery (low frequency; 40kHz) is optimized for cell survival, and nanoparticle activation enabled ES throughout the spheroids during differentiation, tissue formation, and maturation. The resultant human neural tissues represent the first example of direct tissue loading with piezoelectric particles for ensuing 3D ultrasound-mediated piezoelectric enhancement of human neuronal induction from stem cells, including augmented neuritogenesis and synaptogenesis. It is anticipated that the platform described will facilitate advanced tissue engineering and in vitro modeling of human neural (and potentially non-neural) tissues, with modeling including tissue development and pathology, and applicable to preclinical testing and prototyping of both electroceuticals and pharmaceuticals.

Fully biodegradable and self-powered nerve guidance conduit based on zinc-molybdenum batteries for peripheral nerve repair

Peripheral nerve injury (PNI) poses a significant public health issue, often leading to muscle atrophy and persistent neuropathic pain, which can drastically impact the quality of life for patients. Electrical stimulation represents an effective and non-pharmacological treatment to promote nerve regeneration. Yet, the postoperative application of electrical stimulation remains a challenge. Here, we propose a fully biodegradable, self-powered nerve guidance conduit (NGC) based on dissolvable zinc-molybdenum batteries. The conduit can offer topographic guidance for nerve regeneration and deliver sustained electrical cues between both ends of a transected nerve stump, extending beyond the surgical window. Schwann cell proliferation and adenosine triphosphate (ATP) production are enhanced by the introduction of the zinc-molybdenum batteries. In rodent models with 10-mm sciatic nerve damage, the device effectively enhances nerve regeneration and motor function recovery. This study offers innovative strategies for creating biodegradable and electroactive devices that hold important promise to optimize therapeutic outcomes for nerve regeneration.

Adherence and retention of elderly people in physical exercise

Background: The combination of aerobic exercise and transcutaneous microcurrent electrical stimulation (MES) application was shown to have a positive effect on localized abdominal adiposity (LAA) reduction. However, the effect of the combination of MES and high-intensity interval training (HIIT) is still unknown. Objective: This study aimed to evaluate the effect of combination of MES and HIIT on LAA reduction. Methods: 39 sedentary women with LAA, distributed in a control group (CG), an exercise group (EG), and a MES plus exercise group (MEG) participated in this randomized clinical trial. The CG was not submitted to intervention. The EG was submitted to a HIIT protocol (80% of heart rate max in a functional circuit) and MEG was submitted to abdominal transcutaneous application of MES prior to HIIT, 2x/week, during 5 weeks. The outcomes were collected by a blind evaluator and measured in three moments (before the 1st intervention, and after the 5th and 10th intervention), based on body composition parameters, anthropometric data, physical activity level (PAL), body satisfaction, quality of life (QOL), and lumbar functionality. Results: After 10 interventions, MEG showed significant improvement in skinfolds, QOL, and body satisfaction, but no significant difference compared to EG or CG. Regarding PAL, MEG differed significantly in relation to CG, but not in relation to EG. Conclusion: The combination of MES and HIIT in 10 interventions did not show satisfactory results for LAA reduction compared to HIIT, but the increase in PAL and the improvement in lumbar functionality may provide positive effects in the medium-term, although further studies are required.

Application of electrostimulation and magnetic stimulation in patients with optic neuropathy: A mechanistic review.

Visual impairment caused by optic neuropathies is irreversible because retinal ganglion cells (RGCs), the specialized neurons of the retina, do not have the capacity for self-renewal and self-repair. Blindness caused by optic nerve neuropathies causes extensive physical, financial, and social consequences in human societies. Recent studies on different animal models and humans have established effective strategies to prevent further RGC degeneration and replace the cells that have deteriorated. In this review, we discuss the application of electrical stimulation (ES) and magnetic field stimulation (MFS) in optic neuropathies, their mechanisms of action, their advantages, and limitations. ES and MFS can be applied effectively in the field of neuroregeneration. Although stem cells are becoming a promising approach for regenerating RGCs, the inhibitory environment of the CNS and the long visual pathway from the optic nerve to the superior colliculus are critical barriers to overcome. Scientific evidence has shown that adjuvant treatments, such as the application of ES and MFS help direct thetransplanted RGCs to extend their axons and form new synapses in the central nervous system (CNS). In addition, these techniques improve CNS neuroplasticity and decrease the inhibitory effects of the CNS. Possible mechanisms mediating the effects of electrical current on biological tissues include the release of anti-inflammatory cytokines, improvement of microcirculation, stimulation of cell metabolism, and modification of stem cell function. ES and MFS have the potential to promote angiogenesis, direct axon growth toward the intended target, and enhance appropriate synaptogenesis in optic nerve regeneration.

Current advances of chlorinated organics degradation by bioelectrochemical systems: a review.

Chlorinated organic compounds (COCs) are typical refractory organic compounds, having high biological toxicity. These compounds are a type of pervasive pollutants that can be present in polluted soil, air, and various types of waterways, such as groundwater, rivers, and lakes, posing a significant threat to the ecological environment and human health. Bioelectrochemical systems (BESs) are an effective strategy for the degradation of bio-refractory compounds. BESs improve the waste treatment efficiency through the application of weak electrical stimulation. This review discusses the processes of BESs configurations and degradation performances in different environmental media including wastewater, soil, waste gas and groundwater. In addition, the degradation mechanisms and performance-enhancing additives are summarized. The future challenges and perspectives on the development of BES for COCs removal are briefly discussed.

Electrical Stimulation and Motor Function Rehabilitation in Spinal Cord Injury: A Systematic Review.

Spinal cord injury (SCI) often leads to devastating motor impairments, significantly affecting the quality of life of affected individuals. Over the last decades, spinal cord electrical stimulation seems to have encouraging effects on the motor recovery of impacted patients. This review aimed to identify clinical trials focused on motor function recovery through the application of epidural electrical stimulation, transcutaneous electrical stimulation, and functional electrical stimulation. Several clinical trials met these criteria, focusing on the impact of the aforementioned interventions on walking, standing, swimming, trunk stability, and upper extremity functionality, particularly grasp. After a thorough PubMed online database research, 37 clinical trials were included in this review, with a total of 192 patients. Many of them appeared to have an improvement in function, either clinically assessed or recorded through electromyography. This review outlines the various ways electrical stimulation techniques can aid in the motor recovery of SCI patients. It stresses the ongoing need for medical research to refine these techniques and ultimately enhance rehabilitation results in clinical settings.

Prospect of value and application of transcutaneous electrical acupoint stimulation to control blood pressure in proactive healthcare perspective.

Hypertension is a global problem threatening human health and life. Although there are many antihypertensive drugs, the low compliance of medication affects its efficacy, and the effect in regulating hypertension has become increasingly prominent. Focusing on the new trend of proactive healthcare management, in the present paper, we made a summary about the status and existing problems of transcutaneous electrical acupoint stimulation (TEAS) in the regulation of blood pressure, and put forward some suggestions, such as selecting acupoints based on classical acupuncture theory to highlight the advantages of TEAS to control blood pressure as a whole, optimizing and screening the parameters of TEAS in the regulation of blood pressure, expanding the research observation indexes etc. We also made a prospect about its future application, hoping to provide new ideas for the proactive regulation, whole-process regulation and integrated regulation of blood pressure.

Analysis of the Improvement Effect of Combined Application of Oral Rehabilitation Training and Neuromuscular Electrical Stimulation on Pediatric Swallowing Disorders

Pediatric swallowing disorders are common yet often overlooked neuro-muscular system diseases that significantly impact the quality of life and development of affected children. This study aims to explore the effect of combined application of oral rehabilitation training and neuromuscular electrical stimulation on improving pediatric swallowing disorders. Children meeting the inclusion criteria for swallowing disorders were divided into control and experimental groups based on different intervention protocols. The experimental group received combined oral rehabilitation training and neuromuscular electrical stimulation, while the control group received only oral rehabilitation training. Results showed that the intervention was more effective in the experimental group, with shorter recovery time for normal swallowing function and improved nutritional status and quality of life. This study provides scientific evidence for clinical treatment of pediatric swallowing disorders. In conclusion, the combined application of oral rehabilitation training and neuromuscular electrical stimulation effectively improves pediatric swallowing disorders, with superior efficacy compared to single treatment methods. Further research is needed to elucidate the mechanism of action and optimize treatment protocols to enhance the therapeutic outcomes and prognosis of pediatric swallowing disorders.
